ATTACHMENT FOR lVIOWING-MACI-IINES.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed March 26, 1914. Serial No. 827,417.

To all whom it may concern Be it known that I, PETER H. KLrnwnn, acitizen of the United States, residing at Woodburn, in the county ofMarion and State of Oregon, have invented certain new and usefulImprovements in Attachments for Mowing-Machines; and I do declare thefollowing to be a full, clear, and exact deto overcome this difficultyby the provision of a plurality of simply constructed attachments whichmay readily be attached and detached and which, when in position, willleave a clearly defined line along the edge of each swath.

To the above end I employ certain novel features of construction andcombination described and claimed in this specification and shown in thedrawings, forming part thereof, and in which- 7 Figure 1 is a plan viewof a portion of a cutter bar showing the application of my improvedattachments thereto; Fig. 2 is an end view of the parts shown in Fig. 1;Fig. 3 is a vertical transverse section on the line 33 of Fig. 1; Fig. 4is a detail longitudinal section on the line 44 of Fig. 1; and Fig. 5 isa detail horizontal section thereof.

In the accompanying drawings, I have shown a portion of a cutter bar Bwhich is provided on its outer end with the usual pointed shoe S andwith'a plurality of forwardly projecting pointed shoes or fingers F. Asclearly shown in the various figures of the drawings, the outer end ofthe cutter bar B passes through an opening 0 in the shoe S and issecured to said shoe by a pair of bolts 5.

Extending forwardly and curving upwardly from the point P of the shoeS,-

isa rod 1 which is of any desired length and diameter and which isenlarged as shown at 2 and the rod is continued rearwardly from theenlarged portion 2 as shown at 3, said rearwardly extending portionsbeing preferably, though not necessarily, square in cross section. Whenthe parts are in position on the mower, the enlarged portion 2 liesslightly in advance of the point P of the shoe S and the portion 3extends rearwardly therefrom substantially in contact with the outerface of the shoe S. When the parts arein this position, a sleeve 4having an elliptical opening 5, is passed over the extension 3 andcontacts, at its forward end, with the shoulder formed by the enlargedportion 2. One side wall of the opening 5 will new contact with theouter face of the rearwardly extending portion 3 and consetween theopposite side wall of said opening and the inner face of the portion 3.This pocket or recess is provided for the reception of the point P ofthe shoe S (see Fig. 5).

For the purpose of maintaining the parts in the position so fardescribed, I provide a clamping post 6 having a rectangular opening nearits upper end, for the reception of the portion 3, the post, above saidopening being slit to provide a pair of ears 7 through which a clampingscrew 8 is passed. By this construction it will be seen that the portion3 is movable within the recess in the post 6. The lower end of said postis provided with an inwardly extending attaching foot 9, the latterbeing provided with an elongated opening 10 which is adapted to bepassed over one of the bolts 7) and to be socured in this position byone of the nuts n on'said bolts. By this construction and ar rangementof parts, it will be readily seen that, when it is desired to remove therod 1, it is simply necessary to loosen the clamping screw 8 whereuponsaid rod 1 and the sleeve 4 may be entirely removed.

The function of the parts so far described, will be hereinafter moreclearly set forth.

For the purpose of raising the fallen grass in advance of the cutter barB, I provide a number of supplemental fingers 11 which, as shown inFigs. 1 and 3, form extensions for the usual shoes or fingers F. Eachfinger 11 provided in its rear end with a socket 12, said. sockets beingadapted to fit snugly over the point P of the fingers F and to besecured in this position by means to be de- 5 scribed.

inclining upwardly and rearwardiy from quently, a recess or socket willremain bei is of suitable length and diameter and is terbar B. i For thepurpose of securely clamping the parts in this position, Iprovide'substantially L-shaped clamping members 17 which are adapted tofit snugly against the rear-ledge of the bar B and to be secured inposition, by clamping screws 18 i which pass loosely through openings inthe upper ends or long arms 23 of said members 17 and are threaded intothe bores-15 of the lugs .14. The outer face of each of the memhere 17is preferably serrated as shown at '19 for coaction with serrations .20formedv on the inner face of a washer 21, the latter underlying the head22 of the screw 18 as clearly shown in Fig. 3. For the purpose ofrendering the clamping members 17, ad-

justable to various thicknesses of cutter bars, I provide the uprightportions or long arms 23 thereof, with inwardly extending lugs 24cwhichare adapted to. coact with clamping screws 25 which are threaded throughthe horizontal portions or short arms 26 of, said members. When theparts extending portions of 'therods 13 in such are in the abovedescribed positions, the shields 16 will overlie the upper-ends-of themembers 17, theheads 22 and washers 21. Thus it will. be seen that theseelements will not retard the forward movement of the cutter bar beneaththe grass which has been cut. Without this provision, it would be proneto catch some of said grass and thus prevent the cutter bar from movingfreely beneath the same.

For the purpose .of preventing the threads of the screws 18, fromcatching in the grass cut, I preferably construct the rearwardly amanner as to provide depending shields 27 which will thus effectuallyprevent this objectionable feature and will also shield the threads ofsaid screw.

When it is desired to remove the fingers 11 it is simply necessary torelease the screws 18 and 25, whereupon the clamping members 17 will befree and the entire devices may be removed.

The fingers 11, may be disposed at suitable intervals throughout thelength of the cutter bar B and it will clearly be seen that they willact to raise any fallen grass and support it in position to be actedupon by t e si l bar t h wn).-

The upwardly curved rod 1 is provided for the purpose of bearing down,lower than the mower knife, and tangled masses of grass that stand andlean over the cutting line of the outer end of the swath. When themasses are thus borne downwardly, the tooth 11, nearest said rod 1, willraise said tangled masses sufficiently to allow the sickle bar toreadily cut the same, thus forming-a clearly defined line along the edgeof each swath and cutting the grass before the wheels of the mower areallowed to pass over the same.

From the foregoing description, taken in connection with theaccompanying drawings, the construct-ion and operation of the inventionwill'be readily understood without requiring a more extendedexplanation.

Various changes info-rm,-proportion and minor details may be resorted towithout departing from the spirit of the invention as claimed.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

'1. A device of the character described comprising a pointed fingerhaving a socket in its rear end, a rod extending rearwardly from saidfinger and having a depending lug provided with a threaded bore,"asubstantially L-shaped clamping member in rear of said lug and having anopening through its upright portion and a screw passing loosely throughsaid opening and engaged with the threads the bore of said I lug.
